Definitions

  • This invention relates to a novel medical instrument. More particularly, this invention relates to a medical instrument which exudes plasticizer only in an extremely small amount and exels in permeability to gas.
  • the blood as widely known, has a self-protective function. On contact with a boundary other than the inner wall of the blood vessel, the blood induces adhesion and aggregate of blood platelets and gelation of blood plasma, namely formation of fibrin cross-links, on the extraneous boundary.
  • blood platelets in the blood aggregate on the boundary of the plastic material of the blood bag so that the ability of blood platelets to aggregate falls, in 6 hours after blood collection, to about 60% and, in 24 hours similarly, to about 40% respectively of the original level existing at the time of blood collection.
  • plastic preserving containers capable of preserving blood for longer periods of time, plastic preserving containers possessed of what is called blood adaptability, or other similar medical instruments, has been winning popoular approval.
  • plastic containers or other plastic medical instruments which are made of flexible vinyl chloride resin are widely used because they are desirable in terms of fabricability, flexibility, transparency, water vapor permeability and resistance to heat.
  • These articles of flexible vinyl chloride resin contain di-2-ethylhexyl phthalate (hereinafter referred to as DOP) and other phthalic esters in proportions of 30 to 60 parts by weight as plasticizer.
  • DOP di-2-ethylhexyl phthalate
  • other phthalic esters in proportions of 30 to 60 parts by weight as plasticizer.
  • the flexible vinyl chloride resin which contains any of the aforementioned phthalic ester type plasticizer does not possess sufficient permeability to gas and the period during which the blood bag made of this resin exhibits the blood platelet preserving property is generally as short as six hours (according to Service Standard of Red Cross Blood Center, the Japan Red Cross Society). It has been known that the blood bag excels in ability to preserve blood corpuscles and blood platelets when it has high permeability to gas [(1) "Platelet Concentrations Stored at 22° C. Need Oxygen"; Jonas Wallvik, Olof ⁇ kerblom; Vox. Sang.
  • TOTM tri-2-ethylhexyl trimellitate
  • Polyester type plasticizers are used as plasticizers of the non-migrating type. It is well known, however, that since these polyester type plasticizers are generally formed preponderantly of fatty esters, they are inferior to phthalic esters having phenyl groups as the chain thereof in terms of resistance to water and resistance to hydrolysis. Further, these plasticizers generally possess high molecular weights and, therefore, exhibit low permeability to gases.
  • a resin composition comprising a blend of 10 to 40% by weight of polypropylene and 40 to 85% by weight of a thermoplastic elastomer has been known to the art (Japanese Patent Application Laid-open No. SHO 55(1980)-60464).
  • Polyolefin type resins possess inferior adhesiveness and, therefore, cannot be fused easily with the high-frequency welder during the second fabrication and do not permit free selection of any desired molding method. They are further destitute of the flexibility possessed by flexible polyvinyl chloride resin.
  • An object of the present invention therefore, to provide a novel medical instrument.
  • Another object of this invention is to provide a medical instrument which exudes very little plasticizer and excels in permeability to gas.
  • a medical instrument molded with a resin composition
  • a resin composition comprising 100 parts by weight of vinyl chloride type resin, 10 to 80 parts by weight of a di-n-alkyl ester of phthalic acid possessing the general formula I: ##STR1## wherein m and n each denotes an integer of the value of 8 to 14 and (m+n)/2 has a value of 9 to 14, and 1 to 18 parts by weight of a stabilizer.
  • This invention is also directed to a medical instrument having 9 to 12 carbon atoms in a straight-chain alkyl group thereof.
  • This invention is further directed to a medical instrument having di-n-decylphthalate as the di-n-alkyl ester of phthalic acid.
  • This invention is directed further to a medical instrument comprising 100 parts by weight of vinyl chloride type resin, 10 to 70 parts by weight of the di-n-alkyl ester of phthalic acid possessing the general formula I, and 2 to 15 parts by weight of a stabilizer.
  • this invention is directed to a medical instrument having an epoxidized vegetable oil and a calcium-zinc type stabilizer as principal components of the stabilizer therefor.
  • the medical instrument of the present invention is a blood bag.
  • This invention is directed to a medical instrument which exudes the di-n-alkyl ester of phthalic acid in only a very little amount.
  • This invention is further directed to a medical container which has a permeability coefficient of 2.5 ⁇ 10 3 ml ⁇ mm/m 2 ⁇ day ⁇ atm (30° C.) with respect to carbon dioxide gas.
  • the drawing is a front view illustrating a typical medical instrument embodying the present invention.
  • vinyl chloride type resin for use in the resin composition of the medical instrument of the present invention, not only homopolymer of vinyl chloride but also polyvinylidene chloride or a copolymer of not less than 70% by weight, preferably not less than 85% by weight, of vinyl chloride with another monomer copolymerizable therewith is desirably used.
  • the average polymerization degree of the vinyl chloride type resin is in the range of 700 to 3,000, preferably 1,000 to 2,400.
  • Examples of the comonomer for vinyl chloride include vinylidene chloride, ethylene, propylene, vinyl acetate, vinyl bromide, vinyl fluoride, styrene, vinyl toluene, vinyl pyridine, acrylic acid, alkyl acrylates (such as methyl acrylate, ethyl acrylate, isopropyl acrylate, n-butyl acrylate and 1-ethylhexyl acrylate), methacrylic acid, alkyl methacrylates (such as methyl methacrylate, ethyl methacrylate and 2-ethylhexyl methacrylate), acrylonitrile and methacrylonitrile.
  • the vinyl chloride resin can incorporate therein styrene-acrylonitrile copolymer or styrene-methacrylonitrile copolymer.
  • the di-n-alkyl ester of phthalic acid usable as the plasticizer is represented by the general formula I. It is used in an amount of 10 to 80 parts by weight, desirably 40 to 70 parts by weight, and more desirably 50 to 60 parts by weight, based on 100 parts by weight of the vinyl chloride type resin.
  • m and n each have a value of 8 to 14, desirably 9 to 12, and most desirably 10, and (m+n)/2 has a value of 9 to 14. If the number of carbon atoms is not more than 7, the produced medical instrument exudes the plasticizer in a large volume.
  • the alkyl ester possesses insufficient plasticizing efficiency and must be incorporated in an excessive amount to confer ample flexibility to the resin composition.
  • the alkyl ester used in an excessive amount is inferior in compatibility with the vinyl chloride type resin and increases the permeability to steam. It has been ascertained, surprisingly, to the inventors that the aforementioned alkyl group, when possessing a branched chain, is incapable of conferring ample permeability to gas upon the resin composition and that the permeability to gas is high only when the alkyl group is in the form of a straight chain.
  • di-n-alkyl ester of phthalic acid possessing the aforementioned general formula I examples include di-n-nonyl phthalate, di-n-decyl phthalate, di-n-undecyl phthalate, di-n-dodecyl phthalate, di-n-tridecyl phthalate, n-octyl-n-decyl phthalate, n-decyl-n-tridecyl phthalate, and mixtures thereof.

  • stabilizers such as a phosphorous ester represented by didecylphenyl phosphite and an another organic stabilizer such as a mixture between stearoyl benzomethane and palmitoylbenzoyl methane are other examples.
  • the amount of the stabilizer to be used generally falls in the range of 1 to 18 parts by weight and preferably in the range of 2 to 15 parts by weight, based on 100 parts by weight of the vinyl chloride type resin.
  • the aforementioned stabilizers are usable singly. It is, however, desirable to use the aforementioned epoxy compound in combination with the metallic soap, phosphorous ester or organic stabilizer.
